The design of three-dimensional turbine
blades combined with profiled endwalls
结合成型端壁的三维涡轮机(透平)叶片设计
Abstract: This paper describes a novel design for reducing secondary flow in turbines.
摘要:本论文描述了关于减少透平二次回流的新颖设计
The design builds on previous work on non-axisymmetric profiled endwalls by combining them
with three-dimensional blade design.
本设计建立在先前非轴对称成型端壁的工作基础上,结合了三维叶片的设计
Profiled endwalls have been shown to effectively reduce secondary flow but have often been used as a ‘retrofit’ application where the blade design is left unchanged.
成型端壁有效地减少了二次回流,但是常常被用作更新应用,叶片设计却未改变。
In the current paper reverse compound lean is used to prepare the blade row for the application of profiled endwalls.
本文中,为了成型端壁的应用,逆弯扭用来装备叶栅。
Computational fluid dynamic predictions of the expected performance show benefits over and above those of applying profiled endwalls to the blade row alone.
流体动力学计算的预测期望性能比单独使用成型端壁的叶栅要好
The paper describes the design of the novel geometry for the so-called
‘Durham Cascade’ and gives predictions of the expected performance.
本文描述了‘Durham 叶栅’的新几何参数的设计并预测了期望性能。
